Paternal age effect

Introduction

The paternal age effect describes the influence that a father’s age has on the chances of conferring a genetic defect to his offspring. Generally, older men have a greater probability of fathering children with a genetic defect than younger men do. This is seen as likely due to genetic copying errors which may increase in number after repeated spermatogenesis cycles over a man’s lifetime.
